ASTM D1938Standard Test Method for Tear-Propagation Resistance (Trouser Tear) of Plastic Film and Thin Sheeting by a Single-Tear Method
ASTM D1938 covers the determination of the force necessary to propagate a tear in plastic film and thin sheeting by a single-tear method. It rates the tear-propagation resistance of various plastic films and thin sheeting of comparable thickness.
Before conducting ASTM D1938, it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
